I'm filling out a chart where a DNA sequence is given and we have to fill in the mRNA and tRNA anticodon blanks. Will the tRNA anticodon always match the DNA sequence? One word answers will be ignored. =p

Thanks for your time and intellect! lol

No, the tRNA anticodon will *not* always match the DNA sequence, for at least two reasons. One is that some tRNA anticodons contain nonstandard bases (e.g. inosine). The other is what's called the Wobble Hypothesis.

To answer your question, the codon is on the mRNA strand, and so the anticodon (the complementary sequence) is on tRNA (transfer RNA). There is also one more pair worth knowing: DNA has two strands, the sense and antisense strands. The sense strand has the same sequence as the mRNA, while the antisense is complementary. Hence the mRNA is copied from the antisense strand (so it has the same sequence as the sense strand), and hence the antisense strand has the same sequence as the anticodon.

DNA is double stranded, and whether it matches with tRNA or not depends on which strand of the DNA is transcribed into mRNA.
Since the mRNA is an anti-codon of the DNA strand being transcribed, and tRNA is an anti-codon of the mRNA, it will match the original DNA template with U replacing T.

The tRNA will match the DNA, except DNA's T (thymine) will be tRNA's U (uracil).

tRNA will match the sequense of the mRNA....Adenine with uracil and Guanine with Cytosine, and then theu code fore specific proteins.
